But, the allergist also explained to
me that they cannot and do not test for allergies to
various chemicals, many of which are present in wine, and other things we drink or eat. Eating organic food is a start, and I have had to cut out drinking wine. Also, I agree with the other posts that suggest that dairy products such as milk, cream, cheese, sour cream, etc. also cause an increase in phlegm. First, I'd cut out alcohol for a couple of weeks to see what happens.
